muestran :une s, 193.5, semi No. 24.182 7 claims. (cazo-sam This invention relates to improvements in cyl- Inder sleeve presses for pressing replacement sleeves into cylinder blocks. When a cylinder has cracked or become deeply scored it is remedied and made as good as new by pressing 'thereinto a'sleeve, the cylinder having been bored -1/4" to receive the same. It is the purpose of the present invention to provide means for readily inserting such sleeve.

One object' is to provide a sleeve press that is readily portable and that may be applied to the cylinder bloc` without the use of tools of Vany kind. A i er object is to provide a press that is very compact in assembly in order that it may be applied as readily to the last cylinder, or the one farthest from the radiator, as to any other cylind'er of the block.

A further object is to provide a press that may be applied to the block without danger of breaking the same. In the present press the pressure applied to the top of the sleeve is exerted between two resistance points. one above thepressure point and the other resistance point disposed below the pressure point at the bottom or base of the cylinder, both resistance points and the pressure point falling wholly within the plane of the sleeve or oi the cylinder. In this assembly there is no lateral pull upon the cylinder block and breakage o! the same is not possible.

With the foregoing and other objects in view the invention consists in the combination and arrangement oi parts to be hereinafter fullydescribed, pointed out in the claims and illustrated in theaccompanying drawings which form a part ofthis application for patent and in which- Fig. 1 is a perspective view of the sleeve press showing its application to a cylinder block.

8 and by the plate 1 whioli'is secured to the transverse angles 8 connected by bolts 9 to the frame sides. The frame 4, 5 is adapted to stand upon one end resting upon 'the cylinder block about the cylinderunder operation. The frame sides are formed with periorations Il adapted to receive the removable stop pins II for the iioating stop plate IZzthat freely connects the sides of the stationary frame. v

Arranged within the stationary frame is the traveling frame comprising 4'the head plate Il and base plate I4 connected together by the spacer rods I5 that extend through perforations in the plate 'I and have their ends reduced for positive engagement with perforated portions in said plates-I3, Il. The latter plates are shaped for close fitting sliding engagement with the sides 4, 5 of thestationary frame. The base plate I4 is adapted to rest upon the upper end of the replacement sleeve I to directly force the same into the cylinder.

The plate I4 is formed with a central periora= tion I8 that is in line with and oi' the samediameter as a similar perforation in the plate I to receive a guide bolt II, threaded at its ends, that passes entirely and centrally through the replacement sleeve and through the cylinder and to the lower end oi' which outside the bottom of the cylinder the washer I8 is applied that abuts the base of the cylinder block at the lower end oi the cylinder, a nut I9 threaded upon the bolt I'I retaining said washer in position. A nut 20 at the upper end ofthe bolt Il resting upon the plate I holds said members together. An hydraulic ram or an ordinary automobile jack ox like tool (not shown) is placed upon the head plate I3 with its plunger engaging the stop plate or resistance plate I2. 'I'his jack or tool is placed centrally of the plate I8 so that it is in line with the bolt I1. When the jack, or ram, is manually operated it will force the travelling frame downward within the stationary irame thus pressing the sleeve 3 into the cylinder. The points of resistance. which are the nuts I9 and 20 and that portion oi the plate I2 engaged by the ram ol jack, and the point ot pressure exerted by the razr or jack u n the plate I3 all fall within and centrally oi the sleeve and cylinder so that no side pressure is set up outside the press which greatly reduces the strain upon the cylinder block and prevents otherwise possible breakage of the same The bolt I1 centers the travelling frame with respect to the stationary frame. In operation the jack or ram supports the floating stop plate Il while the stop pins II prevent its riding upward above said pins. As the sleeve is forced into the cylinder the jack or ram becomes extended to its limit and at such time the plate i! and pins Il are moved down to permit disposal of the pins into the lower set o! perorations il` when the operation. is repeated until the sleeve is forced completely into the cylinder. In applying the press to the cylinder block it is merel? set upon the same about the cylinder under operationl and the-bolt i1 and anchormeans I8. il will positively hold it in this position while the operation is being performed. Nor is it necessary that the washer It be tightened nrmly against the base of the cylinder block. It need only be disposed so retained by the nut.
